Crypto rounding: accumulate Bitcoin with every purchase

Every time you pay with your Deblock card, the spare change is automatically converted into Bitcoin. Effortlessly, without thinking about it.

A concrete example

Here is what a normal day looks like:

Morning coffee€3.40€4.00+€0.60
Lunch€14.10€15.00+€0.90
Evening grocery€22.55€23.00+€0.45
Daily total+1,95 €

That is €1.95 automatically invested in Bitcoin that day, without making any conscious decision.

Two rounding modes

Basic rounding

Rounded up to the next euro. You pay €3.40 → the remaining €0.60 is converted into Bitcoin.

Boosted rounding

Rounded up + 1 to 5 extra euros of your choice. To accumulate Bitcoin faster.

Why it is smart

Passive by nature

No action required. Bitcoin accumulates automatically with every purchase.

Natural DCA

Multiple small purchases a day = multiple different entry prices, smoothing your average cost over time.

Direct ownership

The Bitcoin you buy goes into your Deblock wallet. You are the sole owner.

Special case — French Polynesia and New Caledonia: rounding is done in Pacific francs (XPF). The rule is the same: rounded up to the next multiple of 50 XPF (e.g. 1,200 XPF → 1,250 XPF). The boosted mode allows adding 100 to 500 extra XPF.
